MSSQL查询数据库表数据大小等情况

1.查询数据库大小

SELECT 
    DB_NAME(database_id) AS '数据库名',
    [Name] AS '逻辑库名',
    [Physical_Name] AS '物理文件',
    ((size * 8) / 1024) AS '文件大小(MB)',
    [differential_base_time] AS '基准时间'
FROM sys.master_files
WHERE DB_NAME(database_id) like 'FuZhou%'

 

2.查询数据库表大小

if exists(select 1 from tempdb..sysobjects where id=object_id('tempdb..#tabName') and xtype='u')
drop table #tabName
go
create table #tabName(
tabname varchar(100),
rowsNum varchar(100),
reserved varchar(100),
data varchar(100),
index_size varchar(100),
unused_size varchar(100)
)
 
declare @name varchar(100)
declare cur cursor for
select name from sysobjects where xtype='u' order by name
open cur
fetch next from cur into @name
while @@fetch_status=0
begin
    insert into #tabName
    exec sp_spaceused @name
    --print @name
 
    fetch next from cur into @name
end
close cur
deallocate cur

select tabname as '表名',rowsNum as '表数据行数',reserved as '保留大小',data as '数据大小',index_size as '索引大小',unused_size as '未使用大小'
from #tabName
order by tabname asc, data desc
